The department was first organized in 1859 and granted a charter by the Massachusetts legislature in 1874. The department disbanded in 1959. Like many salvage corps, the employees were not employed by the city.

During the department's heyday, it had 3 stations, usually old firehouses. In 1911, the department had 61 employees, which consisted of a superintendent, three captains, six lieutenants, 33 permanent men and 18 auxiliaries.
